Description
Technical field
The utility model relates to a kind of water-level gauge of measuring boiler drum level, specifically relates to a kind of guided wave radar senior middle school low pressure two-colour fluviograph of measuring boiler drum level.
Background technology
Water-level gauge for boiler-steam dome level gauging, common are two-colour fluviograph and magnetic float gauge.The liquid level that two-colour fluviograph is measured liquid in boiler-steam dome is according to law of connected vessels, water-level gauge body is connected by steam inlet pipe and feed tube with drum, in liquid level gauge, the height of liquid level is the height of liquid level in boiler-steam dome, according to optical principle, produce gas redder, the effect that liquid is green and then demonstrate the height of liquid level in boiler-steam dome, but the seal of double colored indicator view window and thermal insulation barriers are mainly mica sheet materials, the serviceable life of mica sheet material is shorter, be generally about half a year, therefore need the frequent mica sheet material spare part of changing double colored indicator, increased on the one hand workman's labour intensity, also improved in addition the maintenance cost of double colored indicator.Magnetic float gauge is also to utilize law of connected vessels by steam inlet pipe and feed tube and drum formation linker, according to the magnet rotor of water level display on body, produce the height of liquid level in upset and then definite boiler-steam dome because of the magnetic fields with float again, owing to being high temperature and high pressure environment in boiler-steam dome, the proportion of water changes larger under high-temperature and high-pressure conditions, the buoyancy of corresponding generation also has larger variation, magnetic float is more big changes by the corresponding height floating of the impact of buoyancy, causes the liquid level of measurement inaccurate.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of guided wave radar senior middle school low pressure two-colour fluviograph, the precision of measuring liquid level while using the utility model to measure boiler-steam dome liquid level can not be subject to high temperature and high pressure environment in boiler-steam dome to be affected and need not frequently change liquid level gauge spare part, and liquid level measurement precision is high, easy to maintenance.
For solving the problems of the technologies described above, the utility model guided wave radar senior middle school low pressure two-colour fluviograph, comprise balance pipe and measuring tube, described measuring tube has top cover, on top cover, guided wave radar material level gauge is equipped with in sealing, guided wave radar material level gauge has instrument and rod-type probe, rod-type probe extend into the bottom of described measuring tube, the upper and lower of described balance pipe the same side is provided with steam inlet pipe and the feed tube for being connected with boiler-steam dome, the upper and lower of the opposite side that it is relative is connected with described measuring tube by steam valve and water valve, described water valve is connected with the first blowoff valve, the bottom of described measuring tube is connected with the second blowoff valve.
Adopt the guided wave radar senior middle school low pressure two-colour fluviograph of said structure, steam inlet pipe and feed tube by balance pipe during use are connected with boiler-steam dome, and then make the utility model and boiler-steam dome form linker structure, liquid level in measuring cylinder is consistent with the liquid level in boiler-steam dome, the high-frequency pulse signal that sealing is arranged on the instrument generation of the guided wave radar material level gauge on measuring tube top cover is transmitted to rod-type probe, and propagate along probe, pulse signal reflects on liquid level surface, reflected signal is received by instrument, being converted into thing position information provides, the utility model is because measuring principle is simple, be not subject to the impact of process condition, thereby measuring accuracy can not be affected yet, and Installation and Debugging are easy, maintenance cost is low.Balance pipe can play the effect of stablizing liquid level in addition, makes the utility model more accurate to the measurement of liquid level in liquid boiler-steam dome, and blowoff valve can play the effect of regular discharge water dirt.
As further improvement of the utility model, also comprise for showing the double-colored light beam Displaying Meter of water level, the signal output part of the instrument of described guided wave radar material level gauge is connected with the signal input part of double-colored light beam Displaying Meter, and the instrument of guided wave radar material level gauge is loaded on the housing of double-colored light beam Displaying Meter.By increasing double-colored light beam Displaying Meter, can make the utility model more directly perceived to the observation of liquid level, can be compared with distant surveillance liquid level of steam drum, the instrument of guided wave radar material level gauge is arranged on the housing of double-colored light beam Displaying Meter, can avoids the interior high-temperature water heat radiation of measuring cylinder to damage the instrument of described guided wave radar material level gauge.
The utility model can also combine with remote supervision system, and the instrument signal output terminal of guided wave radar material level gauge of the present utility model is connected with remote supervision system, realizes remote monitoring, long-range demonstration.
